Re: using bb_get_profile_link
bbPress functions with the word “get” in them do not self-echo, they simply return the string. So you have to add echo. You almost have it, for example, this should work:
<a href="<?php echo bb_get_profile_link(); ?>">My Profile</a>
And just to confuse you, there are a couple of legacy functions with the word “get” in them that do echo. But they shouldn’t and are rare so don’t worry too much, lol.
